In late June 2017, a forest fire occurred in Doñana Natural Park, which is located in southwestern Europe. Many animal and plant species, some of which are threatened, suffered from the impact of this fire, and important ecosystems in the European Union were seriously affected. This forest fire occurred under exceptional weather conditions. The meteorological situation was studied at both the synoptic scale and the local scale using meteorological fields in the ERA-Interim global model from ECMWF (European Centre for Medium Range Weather Forecasts), the WRF (Weather Research and Forecasting) mesoscale model and ground observations collected at El Arenosillo observatory. Anomalies were obtained using records (observations and simulations) over the last two decades (1996–2016). An anticyclonic system dominated the synoptic meteorological conditions, but a strong pressure gradient was present; positive high pressure anomalies and negative low pressure anomalies resulted in intense NW flows. At the surface, wind gusts of 80 km h⁻¹, temperatures up to 35 °C and relative humidity values <20% were observed. In terms of anomalies, these observations corresponded to positive temperature anomalies (differences of 12 °C), positive wind speed anomalies (>29 km h⁻¹) and negative relative humidity anomalies (differences of 40%). The forest fire reached El Arenosillo observatory approximately 8 h after it began. When the fire started, record-setting maximum values were measured for all gases monitored at this site (specifically, peaks of 99,995 μg m⁻³ for CO, 951 μg m⁻³ for O₃, 478 μg m⁻³ for NO₂, 116 μg m⁻³ for SO₂ and 1000 μg m⁻³ for PM10). According to the temporal evolution patterns of these species, the atmosphere over a burnt area can recover to initial atmospheric levels between 48 and 96 h after an event. The impact of the Doñana plume was studied using hourly forward trajectories computed with the HYSPLIT (Hybrid Single-Particle Lagrangian Integrated Trajectory) model to analyse the emission source for the burnt area. The Doñana fire plume affected large metropolitan areas near the Mediterranean coast. Air quality stations located in the cities of Seville and Cadiz registered the arrival of the plume based on increases in CO and PM10. Using CO as a tracer, measurements from the AIRS and MOPITT instruments allowed us to observe the transport of the Doñana plume from the Strait of Gibraltar to the Mediterranean. Finally, after two days, the Doñana forest fire plume reached the western Mediterranean basin.

2017年6月下旬，位于欧洲西南部的多纳纳自然公园发生了森林大火。许多动植物物种受到这场大火的影响，其中一些受到威胁，并且欧洲联盟的重要生态系统受到严重影响。这场森林大火是在异常天气条件下发生的。使用来自ECMWF（欧洲中距离天气预报中心）的ERA-Interim全球模型，WRF（天气研究和预报）中尺度模型和收集的地面观测资料，在天气尺度和局部尺度上对气象状况进行了研究。在El Arenosillo天文台。使用过去二十年（1996-2016年）的记录（观测和模拟）获得异常。反气旋系统主导了天气的气象条件，存在压力梯度；正高压异常和负低压异常导致强烈的西北流。在地面上，观察到阵风为80 km h ^-1 ，温度高达35°C，相对湿度值<20％。就异常而言，这些观测值对应于正温度异常（差异为12°C），正风速异常（> 29 km h ^-1）和负相对湿度异常（差异为40％）。大约8小时后，森林大火袭击了El Arenosillo天文台。起火时，记录设置最大值测定了所有的气体在该位点（具体地，峰99995微克米监测^-3的CO，951微克米^-3用于O-₃，478微克米^-3为NO ₂，116微克米^-3为SO ₂和1000微克米^-3为PM10）。根据这些物种的时间演变模式，事件发生后48至96小时内，燃烧区域的大气可以恢复到初始大气水平。使用HYSPLIT（混合单颗粒拉格朗日算子）计算的每小时向前轨迹研究了Doñana羽流的影响综合轨迹）模型来分析燃烧区域的排放源。多娜那（Doñana）火柱影响了地中海沿岸的大都市地区。塞维利亚和加的斯市的空气质量站根据CO和PM10的增加记录了烟羽的到来。使用CO作为示踪剂，通过AIRS和MOPITT仪器进行的测量使我们能够观察到Doñana羽流从直布罗陀海峡到地中海的运输。最终，两天后，多纳纳（Doñana）森林大火向西地中海盆地扩散。
